Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a divisional of U.S. application Ser. No. 10 / 799,471, filed Mar. 12, 2004. A Notice of Allowance with regard to the preceding application was mailed on Jul. 27, 2006. The specification of the preceding application is incorporated herein by reference.INTRODUCTION [0002] Semiconductor devices are used in a variety of electronic devices. For example, thin-film transistor technology can be used in liquid crystal display (LCD) screens. Some types of thin-film transistors have relatively slow switching speeds because of low carrier mobility. In some applications, such as LCD screens, use of thin-film transistors with relatively slow switching speeds can make it difficult to accurately render motion.BRIEF DESCRIPTION OF THE DRAWINGS [0003]FIGS. 1A-1F illustrate various embodiments of a semiconductor device, such as a thin-film transistor. [0004]FIGS. 2A-2B illustrate a cross-sectional schematic of an embodiment of a thin-fil...
